      OBJECTIVE: Increase in population's longevity has led to considerable efforts worldwide on physical therapy aging research. The aim of this study is to identify which are the main scientific journals, as well as the most productive authors, institutions and keywords related to the journals, that have published about physical therapy and aging.METHODS: Original articles published from 1990 to 2014 were retrieved from the bibliographic database Science Citation Index Expanded of Web of Science Core Collection. After standardization of the bibliographic information, a series of bibliometric indicators was obtained regarding authors, institutions, citation and keywords of the core journals using bibliometric software. The PAJEK network analysis program was used for graphic representation.
    RESULTS: A total of 2,237 original articles are included in this analysis. The number of identified journals is 573, with an average growth of publishing journals throughout the studied period of 9.41%. Bradford's distribution shows 12 core journals, out of which 41.67% have published constantly all throughout the 25-year period, being the most productive one Physical Therapy. Fritz, Julie M is the most productive author, and University of Sydney the most productive institution. The keyword exercise is used in an outstanding way.
    CONCLUSIONS: The productivity trends provided an indication of the greater scientific interest of physical therapy in aging as a line of research. Collectively, the data indicated that physical therapy-specific journals are being consolidated but non-specific are still a significant research source, and that a fundamental element of their research includes exercise and movement.

      Introduction Although there have been important developments in microsurgery in recent years, there is no current and comprehensive bibliometric study in the literature. In this study, we aimed to present a summary of the articles published on microsurgery between 1980 and 2019 with bibliometric analysis. Methods Articles published on microsurgery between 1980 and 2019 were withdrawn from the Web of Science database and analyzed by bibliometric methods. Citation analysis was performed to identify effective journals and articles. Keyword cluster and trends analyses were performed for a detailed analysis of the researched topics. Relationships between the article numbers of the countries and gross domestic product (GDP) and human development index (HDI) values were investigated using Spearman's correlation coefficient. A linear regression analysis was used to estimate the number of articles to be published in the future. Results A total of 3,537 publications related to microsurgery were found. Bibliometric analyses were performed in 2,063 articles (58.3%) of these publications. The most active countries in publishing were the United States (504), Germany (286), and Italy (154), respectively. A statistically significant correlation was found between the article numbers and the GDP and HDI sizes of the countries (r = 0.758, p <0.001, r = 0.659, p <0.001). Conclusion The economic size and development levels of the countries were an important factor in academic productivity in microsurgery. Undeveloped countries should be encouraged by performing multidisciplinary studies in this regard.

      Background: Radiosurgery is an effective, alternative treatment modality in managing patients with cerebral arteriovenous malformations (AVMs). The present study aims to highlight the scholarly impact of the top-100 most cited articles on the radiosurgical management of AVMs.Methods: A title-specific search using the keyword "arteriovenous malformation" was conducted in the Scopus database. The outcome of the search was rearranged based on the citations count. Articles were categorized into four entities; clinical, gamma knife radiosurgery, linear accelerator (LINAC) radiosurgery, and proton beam radiosurgery. The exclusion criteria were applied to spinal or non-intracranial AVM, conference papers, non-English articles predominantly discussing the endovascular or microsurgical management.
    Results: The top-100 articles on the radiosurgical management of AVM were published between 1972 and 2016. Approximately one-third of the publications were produced between 1995 and 2000. The average citations per year for all papers were seven. The most-studied entity was pertinent to the clinical application of gamma knife radiosurgery in AVM (68%). The United States was the most active country in studying the radiosurgical application in AVM. The Journal of Neurosurgery published approximately one-third of the most-cited articles in the list. The top-3 most contributing authors, publishing 80% of articles in the list, were Lunsford et al.
    Conclusion: The radiosurgical management of AVMs evolved significantly throughout the years. Identifications of the publication trends facilitate the acquisition of evidence-based articles for authors investigating various radiosurgical techniques in the treatment of AVMs.

      Objective: The publications of application and development of shock wave therapy showed consistent growth. The aim of this study was to investigate the global status and trends in the shock wave therapy field.Methods: Publications about shock wave therapy from 1990 to 2019 were collected from the Web of Science database. The data were studied and indexed by using bibliometric methodology. For a visualized study, VOSviewer software was used to conduct bibliographic coupling analysis, coauthorship analysis, cocitation analysis, and co-occurrence analysis and to analyze the publication trends in shock wave therapy.
    Results: A total of 3,274 articles were included. The number of publications was increasing per year globally. The USA made the largest contributions to the global research with the most citations (the highest h-index). The Journal of Urology had the highest publication number. The University of California System was the most contributive institution. Studies could be divided into seven clusters: urology, hepatology, cardiology, orthopedics, mechanism research of shock wave therapy, andrology, and principle of shock wave therapy. Orthopedics, andrology, and mechanism research of shock wave therapy could be the next hot topics in this field.
    Conclusions: Base on the trends, shock wave therapy is the theme of a globally active research field which keeps developing and extends from bench to bedside.

      Background/purpose: Bibliometric analysis highlights the key topics and studies which have shaped the understanding and management of a concerned disease. Here the top-cited articles on oral potentially malignant disorders (OPMD) were characterized and analyzed.Materials and methods: A comprehensive search was performed and identified in the Scopus database from 1941 to 10 March 2019 for the 100 most-cited articles on OPMD.
    Results: The number of citations of the 100 selected articles varied from 131 to 1422, with a mean of 240.6 citations per article. Molecular markers/targets, chemoprevention, and early detection and diagnosis of oral cancer were the top-3 study topics, and the proportion of the number of the articles on the top-3 topics and that of the number of citations was 47% and 47.7%, respectively. Moreover, 20 (90.9%) of the 22 high-quality articles published in journals with high IF > 9 were the research of top-3 topics. Besides, the most contributing author, Hong WK (n = 11), was from the most contributing institution and country of origin, M.D. Anderson Cancer Center (n = 12), United States (n = 41). Systematic reviews (n = 7), randomized controlled trial (n = 5), cohort studies (n = 18) were study designs with higher evidence level, but the large majority (n = 70) were considered lower level.
    Conclusion: The results of this first citation analysis of the 100 most-cited articles on OPMD provide a historical perspective and key topics, and suggest a troika for the trends of further research and clinical practice in the field of OPMD.

      Background: There is a crucial link between the gut microbiota and the host central nervous system, and the communication between them occurs via a bidirectional pathway termed the "microbiota-gut-brain axis." The gut microbiome in the modern environment has markedly changed in response to environmental factors. These changes may affect a broad range of host psychiatric disorders, such as depression, by interacting with the host through metabolic, immune, neural, and endocrine pathways. Nevertheless, the general aspects of the links between the gut microbiota and depression have not been systematically investigated through bibliometric analysis. Aim: This study aimed to analyze the current status and developing trends in gut microbiota research in the depression field through bibliometric and visual analysis. Methods: A total of 1,962 publications published between 1999 and 2019 were retrieved from the Web of Science Core Collection. CiteSpace (5.6 R5) was used to perform collaboration network analysis, co-citation analysis, co-occurrence analysis, and citation burst detection. Results: The number of publications has been rapidly growing since 2010. The collaboration network analysis revealed that the USA, University College Cork, and John F. Cryan were the most influential country, institute, and scholar, respectively. The most productive and co-cited journals were Brain Behavior and Immunity and Proceedings of the National Academy of Sciences of the United States of America, respectively. The co-citation analysis of references revealed that the most recent research focus was in the largest theme cluster, "cytokines," thus reflecting the important research foundation in this field. The co-occurrence analysis of keywords revealed that "fecal microbiota" and "microbiome" have become the top two research hotspots since 2013. The citation burst detection for keywords identified several keywords, including "Parkinson's disease," "microbiota-gut-brain axis," "microbiome," "dysbiosis," "bipolar disorder," "impact," "C reactive protein," and "immune system," as new research frontiers, which have currently ongoing bursts. Conclusions: These results provide an instructive perspective on the current research and future directions in the study of the links between the gut microbiota and depression, which may help researchers choose suitable cooperators or journals, and promote their research illustrating the underlying molecular mechanisms of depression, including its etiology, prevention, and treatment.

      Background: This study investigated the trends in the scientific output of Iran published in PubMed indexed journals. To the best of our knowledge, there was no previous study to examine the Iranian scientific output in all fields of health and biomedical sciences. Methods: Using a bibliometric approach, we tracked 140 years (between 1877 and 2016) of Iranian scientific productions in PubMed. The journals which papers widely published over them were analyzed. The metadata of journals was extracted from Web of Science (WoS), Scopus, and Scimago Journal & Country Rank. The Gross Domestic Product (GDP) data was elaborated from the World Bank to evaluate the relationship with research output. We used Pearson's correlation coefficient at p<0.01 significance level and reported the data in a scatterplot. Results: We identified 106 226 documents produced by Iranian authors in journals indexed in PubMed since 1877. The number of papers climbed dramatically in 2000 and afterward, and this was consistent with the country's GDP. Although the scientific contribution of Iranian researchers is remarkable, 67% of papers (26 978 out of 106 226) were published in local Journals categorized into quartile 3 and 4 of WoS and Scopus. The study shows that GDP growth has had a positive influence on publication output (r=0.738, p<0.001). Conclusion: This is the first study with a panorama view of Iran's contribution to biomedical literature. Based on the results of our survey, although the number of Iranian publications rose over time but they are mostly published in low ranked journals. Health policy-makers advise reconsidering the criteria for measuring research activities. Improving policies will help researchers to publish in higher ranked journals.

      INTRODUCTION: Herein, we aimed to compare the scientometric data of hematology journals, and compare the publication models, especially the scientometric data of journals with all-open access (OA) and hybrid-OA publication models.METHODS: Data were obtained from Scimago Journal & Country Rank and Clarivate Analytics InCites websites. Fifty-four journals indexed in Science Citation Index (SCI) and SCI-Expanded were evaluated. Bibliometric data and impact factor (IF), scientific journal rank (SJR), eigenfactor score (ES), and Hirsch (h)-index of the journals were obtained. United States dollar (USD) was used as the requested article publishing charge (APC). Statistics Package for the Social Sciences (SPSS, IBM Corp., Armonk, NY) version 23.0 was used for data analysis.
    RESULTS: As a publication model, Hybrid-OA was the most common. One journal had subscription-only, and two journals had a free-OA model. Nine journals had a mandatory OA with the APC model and 42 journals used a hybrid model. The Median OA fee was 3400 USD. Hybrid-OA journals had a significantly higher median h-index (72 vs. 40, p=0.03) compared to all-OA journals. Other scientometric indexes were similar. When APCs were compared, all-OA journals were median 900 USD lower than hybrid-OA journals (2490 vs. 3400 USD, p=0.019).
    CONCLUSION: There is a widespread use of the OA publication model in hematology journals. Although hybrid OA journals have higher h-index, other scientometric indexes are similar. All-OA journals are more economically feasible considering a lower median APC. Further scientometric studies for journals in the field of hematology, randomized to follow citation per publication according to the OA model would better shed light on the data in this area.

      BACKGROUND AND OBJECTIVE: The implantation of multifocal intraocular lens (IOL) has increased in recent years, allowing patients to achieve good quality vision at all distances, independence from use of glasses, and consequently, an increase in quality of life. The main purpose of this study was to analyse the links between publications and authors via citation networks, as well to as identify the different research areas and determine the most cited publications.MATERIAL AND METHODS: The publication search was performed through the Web of Science database, using the terms «Multifocal intraocular lens», «Bifocal intraocular lens», «Trifocal intraocular lens», «Diffractive intraocular lens», «Refractive intraocular lens», «Accommodative intraocular lens» and «Extended depth of focus intraocular lens», for a time interval from 1989 to August 2020. The software used to analyse the publications was the Citation Network Explorer.
    RESULTS: A total of 1293 publications were found, with 11730 citations generated in the network, and 2019 had the highest number of publications of any year. The most cited publication was «European multicenter study of the AcrySof ReSTOR apodized diffractive intraocular lens» by Kohnen et al., published in 2006. Four groups about different research areas in this field were found using the Clustering functionality: visual quality, IOL designs, ocular aberrations, or defocus curves.
    CONCLUSIONS: The citation network offers an objective and comprehensive analysis of the main articles on the different designs and classes of multifocal IOL.

      This paper gives insights into recent research developments in the field of digital solutions for people with aphasia and tries to analyse its impact on their rehabilitation. A bibliometric research approach is used for data collection. Relevant studies were extracted from seven major academic databases from years 2000 to 2019 inclusive. The systematic process resulted in 986 studies. The average growth in this field is 4%, which is less compared to other research areas. However, the average citations per paper is 7.27, which represents a medium level of publication quality. Scopus and Web of Science are leading databases for the number of studies (379 and 264) and quality of publications (P-Index: 49.26 and 32.85), respectively. The USA, with 42% of publications, leads this research field, followed by the UK with 15%. Both countries have national aphasia strategies in place through charities (not government level strategies), which potentially contributed to their research leadership. The results show that recent advances in digital solutions have the potential to support people with aphasia. However, further work is needed at both academic and government levels to deliver more research contributions and funding for the rehabilitation of people with aphasia.

      BACKGROUND: Inappropriate authors' self-citation (A-SC) is a growing mal-practice possibly boosted by the raising importance given to author's metrics. Similarly, also excessive journals' self-citation (J-SC) practice may factitiously influence journal's metrics (impact factor, IF). Evaluating the appropriateness of each self-citation remains challenging.MAIN BODY: We evaluated the presence of policies discouraging A-SC in Critical Care Medicine (CCM) journals with IF. We also calculated the J-SC rate of these journals. In order to evaluate if J-SC rates are influenced by the focus of interest of CCM journals, we separated them in three sub-categories ("multidisciplinary", "broad" or "topic-specific" CCM journals). We analyzed 35 CCM journals and only 5 (14.3%) discouraged excessive and inappropriate A-SC. The median IF was higher in CCM journals with A-SC policies [4.1 (3-12)] as compared to those without [2.5 (2-3.5); p = 0.02]. The J-SC rate was highly variable (0-35.4%), and not influenced by the presence of A-SC policies (p = 0.32). However, J-SC rate was different according to the focus of interest (p = 0.01): in particular, it was higher in "topic-specific" CCM journals [15.3 (8.8-23.3%)], followed by "broad" CCM [11.8 (4.8-17.9%)] and "multidisciplinary" journals [6.1 (3.6-9.1%)].
    CONCLUSIONS: A limited number of CCM journals have policies for limiting A-SC, and these have higher IF. The J-SC rate among CCM journals is highly variable and higher in "topic-specific" interest CCM journals. Excluding self-referencing practice from scientific metrics calculation could be valuable to tackle this scientific malpractice.

      Many have called for greater inclusion of researchers from low- and middle-income countries (LMICs) in the conduct of global health research, yet the extent to which this occurs is unclear. Prior studies are journal-, subject-, or region-specific, largely rely on manual review, and yield varying estimates not amenable to broad evaluation of the literature. We conducted a large-scale investigation of the contribution of LMIC-affiliated researchers to published global health research and examined whether this contribution differed over time. We searched titles, abstracts, and keywords for the names of countries ever classified as low-, lower middle-, or upper middle-income by the World Bank, and limited our search to items published from 2000 to 2017 in health science-related journals. Publication metadata were obtained from Elsevier/Scopus and analysed in statistical software. We calculated proportions of publications with any, first, and last authors affiliated with any LMIC as well as the same LMIC(s) identified in the title/abstract/keywords, and stratified analyses by year, country, and countries' most common income status. We analysed 786 779 publications and found that 86.0% included at least one LMIC-affiliated author, while 77.2% and 71.2% had an LMIC-affiliated first or last author, respectively; however, analagous proportions were only 58.7%, 36.8%, and 29.1% among 100 687 publications about low-income countries. Proportions of publications with LMIC-affiliated authors increased over time, yet this observation was driven by high research activity and representation among upper middle-income countries. Between-country variation in representation was observed, even within income status categories. We invite comment regarding these findings, particularly from voices underrepresented in this field.

      The field of social sciences has become increasingly important in eHealth. Patients currently engage more proactively with health services. This means that eHealth is linked to many different areas of Social Sciences. The main purpose of this research is to analyze the state-of-the-art research on eHealth from the perspective of social sciences. To this end, a bibliometric analysis was conducted using the Web of Science database. The main findings show the evolution of publications, the most influential countries, the most relevant journals and papers, and the importance of the different areas of knowledge. Although there are some studies on eHealth within social sciences, most of them focus on very specific aspects and do not develop a holistic analysis. Thus, this paper contributes to academia by analyzing the state-of-the-art of research, as well as identifying the most relevant trends and proposing future lines of research such as the potential of eHealth as a professional training instrument, development of predictive models in eHealth, analysis of the eHealth technology acceptance model (TAM), efficient integration of eHealth within public systems, efficient budget management, or improvement in the quality of service for patients.

      The COVID-19 pandemic has affected all aspects of society. Researchers worldwide have been working to provide new solutions to and better understanding of this coronavirus. In this research, our goal was to perform a Bibliometric Network Analysis (BNA) to investigate the strategic themes, thematic evolution structure and trends of coronavirus during the first eight months of COVID-19 in the Web of Science (WoS) database in 2020. To do this, 14,802 articles were analyzed, with the support of the SciMAT software. This analysis highlights 24 themes, of which 11 of the more important ones were discussed in-depth. The thematic evolution structure shows how the themes are evolving over time, and the most developed and future trends of coronavirus with focus on COVID-19 were visually depicted. The results of the strategic diagram highlight 'CHLOROQUINE', 'ANXIETY', 'PREGNANCY' and 'ACUTE-RESPIRATORY-SYNDROME', among others, as the clusters with the highest number of associated citations. The thematic evolution. structure presented two thematic areas: "Damage prevention and containment of COVID-19" and "Comorbidities and diseases caused by COVID-19", which provides new perspectives and futures trends of the field. These results will form the basis for future research and guide decision-making in coronavirus focused on COVID-19 research and treatments.

      Many medical specialties use scientometrics to assess the impact of publications, journals, and authors. The aim of this study was to analyze and compare trends of publications from a hospital medical center to publications from a college of medicine connected to that hospital and compare collaboration rates between them to other domestic and international institutions. We used Elsevier's SCOPUS database to compare Penn State College of Medicine (PSCOM) publications to Hershey Medical Center (HMC) publications, analyzing 31,856 total publications. We hypothesized that HMC and PSCOM have room to improve on both internal and international collaborations. Our results show that despite PSCOM's international collaboration being nearly three times higher than HMC, overall international collaboration is less than 2%, far below the US national average.

      Background: The National Natural Science Foundation of China (NSFC) is an important part of China's innovation system. In the last decade, the pig has become more and more widely used in the field of medical science, especially in otology research.Objective: By analyzing and summarizing the funding information over recent years, we intend to identify the characteristics and trends of funding for research using pig models and provide references for future development.
    Material and methods: This is a comprehensive analysis of features in funding for research projects involving pig models by the NSFC in the past 10 years, with a focus on projects in the field of otolaryngology/head and neck surgery.
    Results: Both the number and amount of funding provided by the NSFC for research involving pig models are on the rise with each passing year. Researchers at the PLA General Hospital have completed a number of studies using miniature pigs in cochlear morphology, electrophysiology, cochlear implantation, cochlear transcription analysis, gene therapy, inner ear disease modeling and Eustachian tube pathology modeling.
    Conclusion: Pigs as an ideal large mammal model are well suited in the current national basic research strategy in China, and can help further strengthen China's leading position in basic research in the world.

      BACKGROUND: Gender disparities still exist in the field of academic surgery. Women face additional obstacles obtaining high-ranking, surgical academia positions compared to men, and this may extend to the appointment of editorial board members. We aim to evaluate the gender distribution of editorial board members, associate editors, and editors-in-chief of top US surgical journals and to recommend interventions, which can promote equitable gender representation among editorial boards.METHODS: The study is a cross-sectional analysis using publicly available data regarding the number and proportion of female editorial board members, associate editors, and editors-in-chief from 42 US surgical journals. Descriptive statistics and linear regression were performed with significance defined as P < .05.
    RESULTS: Of 2,836 editorial board members from 42 US surgical journals, 420 (14.8%) were women. Of 881 associate editors, 118 (13.3%) were women. Only 2/42 (4.8%) of editors-in-chief were women. The mean proportions of female editorial board members and associate editors were 14.5% and 19.5%, respectively. No significant associations were found between the 2019 Scimago Journal & Country Rank indicator nor the 2019 impact factor and the proportion of female editorial board members and female associate editors after adjusting for author H-index.
    CONCLUSION: Gender disparities are evident in academic surgery, and women comprise a minority of US surgical editorial board members, associate editors, and editors-in-chief. The implementation of women mentorship from senior faculty on behalf of senior residents and junior faculty, as well as journal-facilitated pipeline programs, can diversify editorial board members by increasing women representation and reduce disparities in surgical journal editorial boards.

      Including diverse participants in biomedical research is essential to reduce health disparities. We assessed the inclusion of Asians in original research studies conducted in North America and published from 2015-2016 in six high-impact generalist journals: New England Journal of Medicine, Journal of the American Medical Association (JAMA), JAMA Internal Medicine, JAMA Pediatrics, Annals of Internal Medicine, and Pediatrics. We determined race reporting method, participant percentage, and reporting of outcomes or implications of findings for Asians and Asian subgroups. Of 1077 studies, 263 articles (24.4%) identified Asians as a distinct race/ethnicity; the median percentage of Asians per study was 3.8%. Of the 263 articles, 28 (10.6%) studies reported outcomes for Asians; nine (3.4%) articles included information about Asian subgroups. Asians are underrepresented in high-impact medical research studies in North America. Efforts to improve study enrollment, data collection, and reporting of findings of Asians in studies remain essential to improve health outcomes for this population.

      In recent years, natural and manmade disasters such as floods, earthquakes, wildfires, and tsunamis have occurred with human losses and environmental deterioration. Henceforth, to reduce the damage caused by these catastrophic events, the administration and government need to track victims and perform synchronized relief efforts on time at the disaster sites. The promising technologies of Internet communication technology (ICT), like the Internet of things, cloud computing, and data analytics, can assist various phases of disaster management. Moreover, the role of higher education spans all stages of disaster management: preparedness, response, and recovery. As educational and research contributions, higher educational institutes are essentially involved in all the disaster management stages to contribute to society broadly. Henceforth, the scientific analysis of disaster management literature is required to analyze the overall structure and developments in this domain. This study presents a scientometric analysis that evaluates the ICT-assisted disaster management research over the last 15 years (2005-2020). It presents various empirical ways to analyze the evolution, status, and result of ICT-assisted in disaster management research. This study provides extensive insight into the publication growth, citation analysis, collaboration, and keyword co-occurrence analysis for technological trends of the ICT-assisted disaster management research. It identifies key journals, countries, and organizations that significantly contributed to this research domain. Overall, this study presents various patterns, research trends, and collaborations as the basic structure for future research in this field.

      Research integrity (RI) is a continuously developing concept, and increasing emphasis is put on creating RI promotion practices. This study aimed to map the existing RI guidance documents at research performing organisations (RPOs) and research funding organisations (RFOs). A search of bibliographic databases and grey literature sources was performed, and retrieved documents were screened for eligibility. The search of bibliographical databases and reference lists of selected articles identified a total of 92 documents while the search of grey literature sources identified 118 documents for analysis. The retrieved documents were analysed based on their geographical origin, research field and organisational origin (RPO or RFO) of RI practices, types of guidance presented in them, and target groups to which RI practices are directed. Most of the identified practices were developed for research in general, and are applicable to all research fields (n = 117) and medical sciences (n = 78). They were mostly written in the form of guidelines (n = 136) and targeted researchers (n = 167). A comprehensive search of the existing RI promotion practices showed that initiatives mostly come from RPOs while only a few RI practices originate from RFOs. This study showed that more RI guidance documents are needed for natural sciences, social sciences, and humanities since only a small number of documents was developed specifically for these research fields. The explored documents and the gaps in knowledge identified in this study can be used for further development of RI promotion practices in RPOs and RFOs.

      PURPOSE: To investigate gender diversity in editorial boards among a wide range of radiology-related journals, the trend in time, and its association with the journal's impact factor (IF).METHOD: The Journal Citation Reports website was searched for radiology-related journals journals with IF>2.0. Gender of the editor-in-chief and all editorial board members as listed on each journal's official website were determined. Mann-Whitney U test and Spearman's rho test were used for statistical analyses. Current data were compared to historical data.
    RESULTS: Fifty-seven radiology-related journals were included. The names of 4176 persons were extracted. A woman was in charge as the only editor-in-chief in 5 of 57 journals (8.8%). Median percentage of female editorial board members was 21.5% (range 3.2%-52.0%). Female editorial board members were in the majority in only two journals, with proportions of 51.4% and 52.0%. IFs between journals with female and male editors-in-chief were not significantly different (median 3.00, range 2.21-7.82 vs. median 3.31, range 2.02-10.98; P = 0.951). There was no significant association between percentage of female editorial board members and a journal's IF (Spearman's rho = -0.019, P = 0.889). The proportion of women has increased compared to historical data.
    CONCLUSION: Women are underrepresented in a wide range of radiology-related journals. Comparison with historical data shows that the proportion of women on editorial boards has increased. Nevertheless, gender composition of the editorial board shows no association with IF. This suggests similar gender bias exists across a broad spectrum of high impact factor journals, with no added bias in journals with higher IF.

      BACKGROUND: Ambient outdoor air pollution has been identified as a key risk factor for adverse health outcomes and mortality, particularly in low- and middle-income countries (LMICs). Small scale, individual-initiated burning activities are significant contributors to local pollutant emissions but are not well studied. We identified articles that describe small-scale burning interventions in order to characterize current trends, implementation science perspectives, and gaps in the literature.METHODS: We conducted a global search of interventions to reduce ambient air pollution, and then conducted a keyword search among these articles to identify literature regarding interventions to reduce individual-initiated burning. We categorized these articles based on whether burning was discussed as an explicit focus or incidental finding and conducted a full-text analysis. We conducted a supplementary review on anthropological aspects of burning behaviors and burning interventions not captured in our review to inform future recommendations.
    RESULTS: Ten articles describing interventions for small-scale, individual-initiated burning were identified. Four articles examined burning as an explicit focus and six discussed burning as an incidental finding. China was the country most represented in our review. All but one of the articles discussed emissions-related outcomes, while only one article discussed health outcomes. Four articles explored factors affecting implementation of interventions and regulations, but none included implementation as a primary objective. The supplementary review revealed a large amount of literature about burning in the context of spiritual and agricultural practices. However, less is known about everyday burning behaviors, such as trash burning and household burning, as well as reasons why people burn.
    CONCLUSION: There is a paucity of research that explicitly discusses interventions for small scale, individual-initiated burning practices. Gaps remain in interventions in LMICs most affected by individual-initiated burning, particularly in sub-Saharan Africa. Most of the current literature does not analyze factors affecting effectiveness of interventions and regulations and does not clearly identify reasons why people choose to burn. More research is needed on how to effectively implement interventions to reduce individual-initiated burning, as well as to target key geographic regions and burning sources that continue to be neglected.

      Importance: The benefits of responsible sharing of individual-participant data (IPD) from clinical studies are well recognized, but stakeholders often disagree on how to align those benefits with privacy risks, costs, and incentives for clinical trialists and sponsors. The International Committee of Medical Journal Editors (ICMJE) required a data sharing statement (DSS) from submissions reporting clinical trials effective July 1, 2018. The required DSSs provide a window into current data sharing rates, practices, and norms among trialists and sponsors.Objective: To evaluate the implementation of the ICMJE DSS requirement in 3 leading medical journals: JAMA, Lancet, and New England Journal of Medicine (NEJM).
    Design, Setting, and Participants: This is a cross-sectional study of clinical trial reports published as articles in JAMA, Lancet, and NEJM between July 1, 2018, and April 4, 2020. Articles not eligible for DSS, including observational studies and letters or correspondence, were excluded. A MEDLINE/PubMed search identified 487 eligible clinical trials in JAMA (112 trials), Lancet (147 trials), and NEJM (228 trials). Two reviewers evaluated each of the 487 articles independently.
    Exposure: Publication of clinical trial reports in an ICMJE medical journal requiring a DSS.
    Main Outcomes and Measures: The primary outcomes of the study were declared data availability and actual data availability in repositories. Other captured outcomes were data type, access, and conditions and reasons for data availability or unavailability. Associations with funding sources were examined.
    Results: A total of 334 of 487 articles (68.6%; 95% CI, 64%-73%) declared data sharing, with nonindustry NIH-funded trials exhibiting the highest rates of declared data sharing (89%; 95% CI, 80%-98%) and industry-funded trials the lowest (61%; 95% CI, 54%-68%). However, only 2 IPD sets (0.6%; 95% CI, 0.0%-1.5%) were actually deidentified and publicly available as of April 10, 2020. The remaining were supposedly accessible via request to authors (143 of 334 articles [42.8%]), repository (89 of 334 articles [26.6%]), and company (78 of 334 articles [23.4%]). Among the 89 articles declaring that IPD would be stored in repositories, only 17 (19.1%) deposited data, mostly because of embargo and regulatory approval. Embargo was set in 47.3% of data-sharing articles (158 of 334), and in half of them the period exceeded 1 year or was unspecified.
    Conclusions and Relevance: Most trials published in JAMA, Lancet, and NEJM after the implementation of the ICMJE policy declared their intent to make clinical data available. However, a wide gap between declared and actual data sharing exists. To improve transparency and data reuse, journals should promote the use of unique pointers to data set location and standardized choices for embargo periods and access requirements.

      BACKGROUND: Gender-based discrimination and sexual harassment, both implicit and overt, have been reported in academic medicine. This study examines experiences of academic hospitalists regarding gender-based discrimination and sexual harassment.METHODS: A survey was distributed to Internal Medicine hospitalists at university-based academic institutions in the United States. Questions assessed experiences regarding gender-based discrimination and sexual harassment in their interactions with patients, as well as with other healthcare providers (HCPs).
    RESULTS: Eighteen institutions participated in the survey, resulting in 336 individual responses. Female hospitalists more frequently reported inappropriate touch, sexual remarks, gestures, and suggestive looks by patients compared with male peers both over their careers (P < .001) and in the last 30 days (P < .001). Similarly, females more frequently reported being referred to with inappropriate terms of endearment (eg, "dear," "honey," "sweetheart") by patients both over their careers (P < .001) and in the last 30 days (P < .001). Almost 100% of females reported being mistaken by patients for nonphysician HCPs over their careers, compared with 29% of males (P < .001) (76% vs 10%, in the last 30 days; P < .001). Similarly, females more frequently reported sexual harassment over their careers (P < .05) and being mistaken for nonphysician HCPs by colleagues both over their careers (P < .001) and in the last 30 days (P < .001). Females rated their sense of respect both by patients (P < .001) and colleagues (P < .001) lower than males (P < .001). More females than males reported that gender negatively impacted their career opportunities (P < .001).
    CONCLUSION: This survey demonstrates that gender-based discrimination and sexual harassment are commonly encountered by academic hospitalists, with a significantly higher number of females reporting these experiences.
